The present invention relates to an advantageous method, especially if a simple and cost approach to fabricating a micro thin-film structure comprising a mechanic from the back of the substrate. This method is the basis of the p-doped Si substrate 1, and further comprising: n-doped with one or more of a series of grid-like regions (2) of the surface of the substrate, n-doped lattice structure (2) of the underlying substrate region 5 porous etching, n to produce a joint (7) on the doped lattice structure (2), the substrate region (5) of the lower, n first monocrystalline silicon on the doped lattice structure (2) the epitaxial layer ( and a step of growing a 8). The method, n the access portion opening 9 of the cavity 7 without opening the closure via one or more openings (6) has a first epitaxial layer (8) for the growth of the doped lattice structure (2) is designed to form an oxide layer 10 is created in the cavity wall, cavities (7) co-wall oxide layer (10) portion as the back access unit 13, the generation of a is used as an etch stop layer, this oxide layer 10 is characterized in that which is removed in the area of the cavity 7, since the cavity is created, access unit 13 back to the thin-film structure 14 formed on (7).
